To aliwhom it may concern Be it'known that I, EBENEZER MORRIS, a citizen of the United States, residing at Soperton, in the county of Montgomery and State of Georgia, have invented certain new and useful Improvements in Axes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make'and use the same, reference being bad to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in axes and the object in view is to produce a simple and efficient device of this nature having a detachable blade for use in connection with the body portion of the ax.

The invention consists of various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claim.

I illustrate my invention in the accompanying drawings, in which Figure 1 is a side elevation of an ax made in accordance with my invention. Fig. 2 is a top plan view. Fig. 3 is a sectional view longitudinally and centrally through the invention.

Reference now being had to the details of the drawings by letter, A designates an ax head having an opening B formed therein for the reception of a handle and a transverse opening-G from the wall of which leads a longitudinal aperture D, terminating in a transverse groove E formed in one end of the head, the walls of said groove being tapered as shown in the drawings.

The removable blade is designated by letter F and has a shank portion H, which is angular in cross section and conforms to the longitudinal aperture formed in the head and the extreme end of said shank portion is cylindrical and threaded, as shown, for the reception of a nut K which is placed in the transverse opening in the head. Said blade has shouldered portions, inclined to conform to and engage the groove in the end of the aX and, when the nut is screwed on to the threaded portion of the shank of the blade, the latter may be drawn tightly within the groove, thus holding. the same rigidly. By reason of the fact that the Walls of the groove E converge toward each other from the exterior surfaces of the'head A to the aperture D and by reason of the fact that the butt end of the blade F fits snugly in the said groove, the said blade is wedged in position in the groove when the nut K is tightened and completely fills the said groove. Furthermore the connection between the blade and the head is devoid of shoulders having rectangularly disposed surfaces and consequently when the ax is in use, the strain incident to impact when the blade comes in contact with an object is transmitted through the blade in lines or directions toward the shank of the blade and then imparted to the median portion of the head A which is the strongest part of the said head by reason of the presence at that portion of the greatest thickness of metal, thus the strain from the force of impact is not scattered or distributed head but is directed or drawn toward the median portion thereof.

By the provision of an ax made in accordance with my invention, it will be noted that, when the point of the blade wears out or becomes broken, it may be easily replaced by loosening the nut and withdrawing the blade and substituting another, thus appreciably lengthening the life of the ax, makin it necessary only to renew the part whic is made of a proper metal to hold a keen edge.

What I claim to be new is An ax comprising a head having an opening passing transversely through the same and provided at one edge with a groove, there being an aperture connecting the opening with the groove, said aperture being angular in transverse section, the said groove having side walls which converge toward through the E S PA ENT each other from the exterior surfaces of the head to the said aperture, a bladehaving a pyramid-shaped butt which fits snugly in opening.

the said groove of the head', said blade also having at the apex of its butt a noncircular shank which fits snugly in the aperture in h ed; 22 i. amnete rs slt ea hes a k. and yieg."l heg per ur ofthe hwt one fehel'fienga'genfexit withthe side of said In testimony whereof I hereunto aifix my slg'nature in presence of two Witnesses.
